The invention relates to the manufacturing system of the uniform prepreg. And yarn, the thermoplastic resin film, and the release paper are supplied The molding unit: yarn in which the thermoplastic resin is dipped from the molding unit inside the release paper drawn out and which is laminated is laminated in the surface the thermoplastic resin is dipped into yarn it compresses it heats up the yarn, supplied between the heating roller of top and bottom the thermoplastic resin film, and the release paper the heating roller of pair is equipped according to the moving direction of yarn it is heated in the yarn of the center, and the yarn both sides with the heater of the material supplier: inside which it supplies the release paper is located in the thermoplastic resin film, best, the outside both sides have the rotating release paper removing unit: traction roller removes the release paper of the prepreg both sides the collection roller which rotates it organizes the prepreg of the sheet form on the cooling is made up of top and bottom with pair and the diameter the traction roller which is brought into contact with this and rotates is formed and organizing the free flag manufacture system configured with the winding part winding the prepreg drawn out with the traction unit: winding roller rotating with the winding motor draws out the prepreg towing the yarn of the material supplier, the thermoplastic resin film, and the release paper between the traction roller of top and bottom to the molding unit and release paper removing unit and is manufactured and in which the traction roller of the traction unit and heating roller of the molding unit are the same The power is delivered to the traction roller of the traction unit, the collection roller of the release paper removing unit, and the heating roller of the molding unit and the power rotates with the separate main motor and while it moves at the traction roller, and the collection roller and the speed in which the heating roller is uniform the prepreg of the uniform quality can be produced.
